When you press Ctrl+Spacebar, the Snowball translation window should
pop up. There might be a problem with Word 97, as we've only tested
Snowball back to Word 2000, but you might try closing and reopening
both Snowball and Word, or possibly even rebooting, before you give up
hope. Do you have access to a later version of Word?
I doubt you're running Vista if you are using Word 97, but some Vista
users have to use the "Open" command from the Snowball main window to
open their Word files, as Snowball may not always be able to find
running Word windows under Vista.
Please let me know if none of these suggestions help and I'll look
into it some more.
